How To Define Custom Materials In SimScale?


This article will cover frequently asked questions regarding custom materials within SimScale. Additionally, the workflow on how to set custom materials is discussed.

  1. What if we dont have a specific material to choose from SimScale’s material library?
  2. Can we add new materials to the list manually? – Yes
  3. Can we upload material properties into SimScale? – No, users cannot import properties directly into SimScale, but can manually edit the properties to match the required material.

Default Material Library

SimScale provides some commonly used materials like Steel, Iron, Aluminium, etc by default.

Default materials include both solids and fluids according to the analysis type selected.

Custom Materials

To define a specific material in the simulation, pick an existing material and modify the properties.

Modifying Existing Material

As an example, pick Aluminuim from the default list of materials. In order to represent this as the required material (Stainless Steel 316 variant), the properties are modified. The same goes for fluids too.

Users can set the properties of the required Fluid or Solid, then save it for use inside the simulation.


Generally, the material properties are provided by the manufacturers or refered from research journals respective to the application.
